To be honest I suspect a good number of the PRC's eastern neighborhood who might be in the market for a fighter like JF17 will not buy it. The political situation.
The same for some of her land locked neighbors they either are going to buy Russian or American or pickup Gripens. Pakistan is the exception not the rule. Where I suspect FC1/JF17 sales will be best is Africa. I suspect in twenty years African nations will shoot be shooting Tavors, CQ311s, AK100s, SCARH and of course older G3,Fal and AKMs vintage tanks will be replaced with Chinese export models and customized indigenous hot rod versions of classics like the T62.
As Hind will continue in service with Havoc following we will see Z9 and Z10 on African shores and FC1 phasing out mig21 for most well some nations move to J10 export. China has placed a deep interest in Africa for both good and ill. The only two real players are Egypt and south Africa with possible emerging players like Nigeria. Africa is where the military buys for China will be the most lucrative and where I suspect we are going to see a massive Private military contracting market boom. Latin America may buy some but few and far between the only reliable buys are infantry and counter insurgency equipment additionally any buy in Latin America would demand tech and building of plants for indigenous builds. The most reliable buyer is Venezuela who is deep in Russian orbit, second most reliable military spender is Brazil who is in French orbit. Argentina is the most likely entry point but the least likely to spend the money. Most of Latin America will likely be getting F16 or grippen or just not buying.
